Dear Sir,
I have prepared the choice scenario for the case having 5 attributes (with 3 levels and a few with 2 levels) and 5 alternatives using Ngene. I have adopted an efficient design technique to design. The Ngene results in 60 choice scenarios with divided into 10 blocks. One thing I didn't understand is whether we can randomly assign the 60 choice scenarios to respondents, giving each respondent 6 scenarios, without considering the block numbers. Is it mandatory to consider the block numbers and follow the same block numbers for every scenario?
Also,
I got the
D error 0.202252 (is this model is efficient, what will be the minimum d-error to be achieved)
A error 2.179224
B estimate 89.061645
S estimate 126058.409 - This sample is huge...
How to achieve the sample size less when we target for 1000 sample size...
